The data interface includes GHG data received by the UNFCCC secretariat as of 20 October 2014.

The reporting and review requirements for GHG inventories are different for Annex I and non-Annex I
Parties. Annex I Parties report their GHG inventories annually by 15 April. Non-Annex I GHG data are
reported in national communications, which are submitted at different points in time.

Upon entry into force of the Treaty of Lisbon on 1 December 2009, the European Community was replaced
and succeeded by the European Union.

The data are reproduced here as reported, with the exception of corrections of typographical or
calculation errors or omissions. Note also the following:

Because of rounding, totals and subtotals may differ from the sum of the individual components.

In estimation of CO2 emissions using reference approach, Parties first report the
apparent consumption in either physical (bbl, 106l, and grams) or energy (oil eq. and
joules) units and then converted into energy units if it is reported in physical units. The data
interface contains data on apparent consumption as reported and also the converted ones. However,
due to technical reasons, the apparent consumption in energy units is reflected as fuel
consumption.

Three modules of the GHG data interface (Detailed data by Party, Comparison by Gas and Comparison by
Category) use "---" to indicate that no data have been reported; "*" to indicate
that data are reported with notation keys (IE, NA, NE, NO); and "n.a." to indicate that the
selection is not applicable for the Party. For the Flexible queries and Compilation and accounting data
modules, all (no data reported, data reported with notation keys and not applicable) are shown as
blank/empty cells. For the user-defined indicators module, "--" is used to indicate that
either no data are available or the ratio cannot be calculated; "n.a." is used to mean that
the selection is not applicable to the Party.

The country area data was not available in FAO (accessed on 17 October 2014) for Papua New Guinea,
South Sudan and Sudan so the country area data for these Parties are used from last year FAO data
(accessed on 22 May 2013).

GHG Data - UNFCCC

Under the Convention, Parties are grouped together according to differing commitments. Such groups are:

Annex I Parties
include the industrialized countries that were members of the OECD (Organisation for Economic
Co-operation and Development) in 1992, plus countries with economies in transition (the EIT
Parties), including the Russian Federation, and several Central and Eastern European States. This
group can be further sub-grouped into two.

The UNFCCC data interface contains some data on population and gross domestic product (GDP), which are
shown in order to illustrate the national context for GHG emissions/removals. The source of the
population data is the UNSD Demographic Statistics but data are accessed through the Common Database of
the United Nations Statistics Division; the source of the
GDP data (at market prices, constant 2005 US$) is the World Bank. These data are displayed on the
GHG data interface with the kind permission of the United Nations and the World Bank; the United
Nations and the World Bank have regulations concerning the use of their data and these organizations
must be consulted before downloading population and GDP data for further use. The country area data is
taken from the Statistical Database of
the Food and Agriculture Organization of the United Nations (FAO).

Base year data in the GHG data interface relate to the base year under the Climate Change Convention
(UNFCCC), which is a year with a historical level of anthropogenic emissions of greenhouse gases not
controlled by the Montreal Protocol chosen as a reference (Article 4.6 of the Convention). The base
year under the Convention is defined slightly differently than the base year under the Kyoto Protocol.
An exception is made for European Union (15) whereby the base year under the Kyoto Protocol is
displayed. The base year emissions under the Kyoto Protocol are provided in the data interface under
the KP data - UNFCCC
section.

The definition format of data for emissions/removals from the forestry
sector is different for Annex I and non-Annex I Parties. For Annex I Parties, the sector is called Land
Use, Land-use Change and Forestry (LULUCF) whereas for non-Annex I Parties, it is called Land-use
Change and Forestry (LUCF). These two definitions are close but not equivalent.

Annex I Parties report GHG data in the common reporting format (CRF). The CRF data prepared using the
CRF Reporter software are readily available for import into the GHG database. Non-Annex I Parties do
not use the CRF Reporter software because of the difference in reporting requirements and therefore the
GHG data reported by non-Annex I Parties need to be processed manually before the data reported can be
imported into the UNFCCC GHG database and displayed as part of the GHG data interface. Due to resource
limitations at the UNFCCC secretariat, activity data and implied emission factors reported in initial
national communications could not be prepared for import into the GHG database except for six Parties,
which have been selected as test cases. These six non-Annex I Parties are Argentina, Kazakhstan,
Mexico, Mozambique, Uruguay and Venezuela. Activity data and implied emission factors for other
non-Annex I Parties will be added to the data interface, to the extent they were reported and subject
to resource availability.

Some of the source categories under the industrial processes sector have unique country specific
activity data depending on the national circumstances. For such source category, the data interface
does not provide description of activity data and is noted by the generic term 'activity data'.
However, the details on the description of the activity data can be found in the CRF
tables reported by the respective Parties.

As per the decisions
9/CP.2 and
11/CP.4, some of the Parties are allowed to use a base year other than 1990. These Parties and
their base years are Bulgaria (1988), Hungary (average of 1985-1987), Poland (1988), Romania (1989) and
Slovenia (1986).

Decision 26/CP.7 invited
Parties to recognize the special circumstances of Turkey, which place it in a situation different from
that of other Parties included in Annex I to the Convention.

Emission estimates of the 15 member States prior to May 2004 (EU-15) and of EU-28 are reported
separately from those of its individual member States. Both estimates are not included in the Annex I
totals in order to avoid double counting.

Bolivia and Mexico reported in their national communications potential HFC emissions. However, both
Parties included those estimates in their national GHG totals, therefore they are not displayed in the
data interface.

The GHG inventory submitted by Sierra Leone for the period 1990-1995 appears to contain technical
errors, especially for the Agriculture and LUCF Sectors. Therefore, this inventory is currently not
included in the data interface.

Some non-Annex I Parties (Cook Islands, Jamaica, Kiribati, Malawi, Samoa, South Africa and Swaziland)
submitted GHG inventory data in their second national communications; however, because they used the
2006 IPCC Guidelines in estimating GHG emissions/removals these data could not be incuded in the data
interface. The same is true of Mexico's fifth nation communication, which could also not be
included because of the use of 2006 IPCC Guidelines.

KP Data - UNFCCC

Under the Kyoto Protocol, Annex I Parties that are also Parties to the Kyoto Protocol with commitments
inscribed in Annex B to the Kyoto Protocol (Annex B Parties) should submit a national GHG inventory, as
required under the Convention, as well as supplementary information on its implementation of the Kyoto
Protocol that covers the Party's holdings and transactions of Kyoto Protocol units (for the
previous year), and emissions and removals from land use, land-use change and forestry (LULUCF)
activities under Article 3, paragraphs 3 and 4, of the Kyoto Protocol.

Similar to Annex I Parties, Annex B Parties can be sub-grouped into two:

Annex B (Economies in Transition) EITs

Annex B non-EITs

Since this year's reporting includes information for the last year of the first commitment period
of the Kyoto Protocol, accounting quantity data for LULUCF activities are presented on the data
interface for all Annex B Parties.

Belarus was included in Annex B to the Kyoto Protocol with quantified emission reduction commitment of
92 per cent through an amendment to Annex B of the Kyoto Protocol (decision 10/CMP.2). As of this
release, this amendment has not been ratified by a sufficient numer of Parties to enter into force.

For the purpose of reporting under the Kyoto Protocol, the European Union submits two sets of standard
electronic format (SEF) tables -- one for the European Union (15) and another for the European Union
(Community Registry).

Data of the European Union (15) are included in the calculation of the totals for Annex B groups (i.e.
Annex B and Annex B non-EIT), and data of individual member States are excluded. The data of the
European Union (Community Regisry) is also included in the calculation of the totals of Kyoto Protocol
units for Annex B groups.

GHG projections data

The source of information for projections data presented on the data interface are the common tabular
format (CTF) tables submitted by Parties to the secretariat as at 20 October 2014. These submissions
are published here. The
projections data reported in the CTF tables, in particular tables 6(a), 6(b) and 6(c), are accessible
through the Flexible Queries module of the data
interface. For detailed information on how to conduct a query, refer to the online help page.

While the European Union (15) submitted CTF tables, these did not contain projections data, hence no
data is available for this Party.

Projections data are presented for the years 2020 and 2030, and for the following scenarios: 'with
measures' (WM), 'with additional measures' (WAM), and 'without measures' (NM),
where available.

Projections data are provided, to the extent possible, for the following category: energy, transport,
industrial processes, agriculture, LULUCF, waste, and other sectors (i.e. cross-cutting), as
appropriate.

Canada reported their data disaggregated by its economic sectors (i.e. transportation,
emissions-intensive and trade-exposed industries (EITE), oil and gas, electricity, buildings, waste and
other, and agriculture). For purposes of presenting data on the data interface, EITE was included under
the industrial processes sector, while oil and gas, electricity and buildings were included under the
energy sector.

For Bulgaria, the GHG emissions from 'Solvents and Other Product Use' are not reported in the
GHG projections tables so the totals from sectors do not match with the totals from gases in these
tables.

Some Parties reported projections data for the 'other
sectors' category. These Parties, and the definition of this sector, are:

Belgium: reported 'Use of N2O for Anaesthesia (CRF 3)', 'Aviation' and
'Fugitive emissions from fuels (CRF 1B)'; data included under corresponding sector, however
aviation has not been included in the national total.

European Union (28): reported 'CRF 3 + 7'; data included under Other sector

Greece: reported 'Aviation'; data has not been included in the national total.

Ireland: reported 'Aviation in the scope of the EU-ETS'; data has not been included in the
national total.

Portugal: reported 'Aviation'; data has not been included in the national total.

Slovakia: reported 'Aviation'; data has not been included in the national total..

Sweden: reported 'Aviation'; data has not been included in the national total.

Ukraine: reported 'Solvents and Other Product Use'; data included under Solvents and other
product use sector.
